Keith Drury wrote an interesting post a while back entitled: Islamification of American Evangelicalism.
He muses about 6 things we might see if Christians were take pointers from Islam:
1) Elevation of the Father over the other members of the Trinity
2) The glory of God is all that matters.
3) Elevation of males and subordination of women
5) Nationalizing religious values
6) Holy war
He doesn’t mention or even allude to Calvinism in the post, but I definitely see points 1-4 as applicable to the Calvinist system.
Drury is a professor/pastor at Indiana Wesleyan University. If you haven’t checked out his site, give it a look. There’s lots of good stuff there. He is opinionated, yet also has a knack for addressing serious topics in a disarming manner. (note: use IE on his site, firefox doesn’t seem to render pages correctly)
